[Linux] Search by contents of file

It is useful to use a terminal for web development.

IDE can do things you can not do.

For example, you might want to look for a file that contains either a variable name or a function name.

$ grep -r 'apple' ./* 

 

Interpreting the above command means "search for files containing the word apple in all subdirectories including the current path".

From now on, development will be accelerated.
